11 Claims.

This invention relates to a painting machine, and relates more particularly to a machine for painting the tips of pirn tubes or similar yarn holders.

Yarn packages are normally supplied with means for identifying the characteristics, 1. e., twist, denier, count. etc., of the yarn wound thereon. In pirn tubes the identification mark usually takes the form of a painted tip, different colors of paint indicating different yarn characteristics. Heretofore, these tips were painted by hand with a brush or by dipping the same in a vessel containing the coloringmedium. The manual pirn tube tip painting was a slow and laborous process. It is, accordingly, an important object of this invention to provide an improved means for coloring'the tips of pirn tubes automatically and expeditiously. 7

Another object of this invention i to provide a machine for automatically coloring the tips of pirn tubes which obviates the use of a brush for applying coloring matter to said tubes.

Still another object of this invention is to provide, in a machine for coloring the tips of pirn tubes, means for positively drying the colored pirn tip before it leaves the machine.

Other objects of this invention, together with certain details of construction and combinations of parts, will appear from the following detailed description.

In the accompanying drawings wherein the preferred embodiment of this invention is shown:

Figure 1 is a side elevational view of the machine of this invention,

Figure 2 is a top, plan view of the same,

Figure 3 i across sectional view, taken on line 33 in Figure 2, on an enlarged scale, and

Figure 4 is a vertical sectional view through the machine.

Like reference numerals indicate like parts throughout the several views of the drawings.

In one aspect, this invention comprises a framework on which is suitably mounted a carrier having an orbital movement for conveying the pirns past a number of stations whereat the tips of the pirns are painted, the excess paint removed and the painted tips dried.

Referring now to the drawings, the reference numeral 5 generally indicates a channel-iron framework which is carried on'a support 6. Fixed at one end of framework 5 is a bearing bracket I having bearings 8 in which is journaled a vertical shaft 9 on the upperextremity of which is mounted a pulley II. This pulley is driven by means of a motor l2connected by belt l3 and pulgear reducer generally indicated by reference numeral IT. The slow speed shaft l8 of the worm gear reducer I1 i vertical and is directly connected by means of a flexible slip coupling, generally indicated by reference numeral I9, to the shaft 9 of the driven pulley l I. The slip coupling I9 is provided as a safety link'in case of' jamming or trapping of the operator's hand in the apparatus. The motor and reducer are carried ona platform supported by legs 6.

At the end of the framework opposite to end carrying shaft 9 is mounted a table 2| having thereon bearing bracket 22 integral with which leys l4 and 15 to worm shaft it of a duplex worm are bearings 23. In these bearings 23 is journaled vertical shaft 24 of idler pulley 25. An endless belt 26 is mounted on pulleys H and 25 which may be flanged to maintain the belt thereon. The table 2i may be moved along framework 5 by means of a screw bolt 26' carried on a crosspiece 21 and attached to the table, the table being secured in any desired position by locknuts' 28 on the screw bolt 26 as well as bolts 29 passing through slots 3| to fasten the table 2| to framework 5. The mounting of the idler pulley 25 on adjustable table 2| permits of the ready tighteningof belt 26. y

The belt 26 carries a series of clips 32 adapted "to hold loosely pirn tubes 33 in such a manner that the shoulder 34 of the ferrule 35 rests on the top of the clip. The pirn tubes 33 are loaded manually in the clips 32 as they come around the drive pulley II and, as-the belt 26 rotates in a clock-wise direction, the tips of the pirn tubes enters between two bent metal strips 31 forming a ramp which the shoulder 34 of the ferrule engages and slides upward the distance necessary to clear the edge 31 of a trough 38 containing the paint to be applied'to the pirn tube tips. The

ramp 3'! is of such length and of such construction as to permit the pirn tubes to fall off the same on to the clips after the edge of the paint trough 38 has been cleared. Supported by the clips 32, the pirn tube tips are immersed to the desired depth in the paint in the trough 38. The' extent of immersion of the tip in the paint trough maybe adjusted if desired.

While the pirn tube travels along in paint trough 38, it i preferably rotated. To this .end there is provided a. rubber covered rod 39 resiliently held against the travelling pirn tubes by a bent wire 4| suitably fixed to a support 42' attached to framework 5. The light pressure of rod 35 against the pirn tubes as they are carried past said rod causes the pirn tubes to rotate insuring uniform application of paint to the tips thereof. After travelling a short distance, say, about two inches, through the paint, the pirn tubes are again raised by a ramp 43 similar in construction and operation to the ramp formed by metal strips 31. Ramp 43 causes the pirn tubes to clear the other edge 44 of paint trough 38, the pirn tubes then dropping on to clips.

The belt 26 then carries the pirn tubes under an air jet 45 (shown closed in Figure 1 and open in Figure 3) which blows air through the opening in the pirn tube thus blowing out any paint collected in the tip opening. This paint is collected in a suitable vessel 46 and reclaimed.

The pirn. tubes then pass around idler pulley 25 to the opposite side of the machine where means are provided for drying the painted tips .of the pirn tubes. This means comprises a fairly long U-shaped trough 41 of a suitable metal, preferably lined with asbestos sheeting 48, carried by a series of bolts 49 adjustably mounted on a bracket fixed to framework 5. The drying trough is provided with heating means 52 in the form of electric strip heaters placed along the bottom thereof. After the pirn tubes emerge from the drying trough 41, they are automatically discharged from the clips by means of one or more stationary fingers 53 and may fall and be collected in any suitable container.

Means are provided at various parts of the machine to prevent the pirn tubes from falling out of the clips. Such means are bent wire guards 54 positioned one on each side of ramp 36 and rods 55, 56 and 51. Rods 55 and 51 are supported from framework 5 by means of bent rods 58 and rod 56 is supported by bent rods 59 attached to cross-pieces 6| and 62 On a bracket 63 fixed to framework 5.

Paint or coloring matter is supplied to paint trough 38 from a glass bottle 64 carried in a cradle 65 mounted on a suitable support 66. This support, together with the cradle and bottle, may be vertically adjustable by raising 0r lowering the screw-bolts 61 by which the support is fixed to and carried above the framework 5, the screwbolts being maintained in adjusted position by means of locknuts 68. The bottle 64 is provided with glass tubes 69 and H extending into trough 36 for supplying paint thereto and maintaining the desired level of paint therein.

While this machine has been described in connection with the painting of pirn tube tips, it is also applicable to the painting of the tips of any yarn holders having a shoulder thereon which could be supported in the clips.

It is to be understood that the foregoing detailed description is given merely by way of illustration and that many variations may be made therein without departing from the spirit of ou'r invention.
